AI Racing
Fixed an issue where AI Drivers could fail to post Qualifying times if the player advanced the event too quickly. The AI Drivers now operate at simulated lightning speed, and will post Qualifying times.
In AI Solo events, when the player quits the race between the green and checkered flags, the AI race results are estimated. An error in lap counting resulted in an underestimation of the laps completed by the AI. The error had no impact if the player quit during the first lap, but the effect was exaggerated the later into the event the player quit in the race. This error is fixed.
- CosmeticAI Drivers have improved their opening lap timesthey are better able to handle the tire and surface temperature changes throughout the course of their first laps.
AI Drivers have improved their racing skills at The Milwaukee Mile.
Physics
The Engine Power Adjustment for Balance of Performance (BoP) setting may now be set to values greater than 100%, increasing the car's engine power. Previously, only values less than 100% were allowed.
Allowable Engine Power Adjustment range is now between 90% and 110% of the original vehicle engine power.
For Official Series and Sessions, the engine power percentage may also be adjusted within the same values, and the value should appear in the BoP for the event.
Hosted Sessions can now also select an engine power percentage from 90% to 110%.
During a test Session, the Engine Power Adjustment may be selected in the Garage.
The Vehicle Weight Adjustment for Balance of Performance (BoP) setting may now be set to negative values, decreasing the vehicle’s mass. Previously, weight was only able to be added to vehicles.
Allowable Vehicle Weight Adjustment range is now between -50Kg and +250Kg of the original vehicle weight.
For Official Series and Sessions, the vehicle weight adjustment may also be adjusted within the same values, and the value should appear in the BoP for the event.
The ability to select vehicle weight adjustments between -50Kg and +250Kg while creating Hosted Sessions will be added shortly.
During a test Session, the Vehicle Weight Adjustment may be selected in the Garage.
User Interface
For the Throttle/Brake UI Widget, a new Graph Length option has been added which now supports up to 30 seconds of playback time.
For the Throttle/Brake UI Widget, a new "Graph Horizontal Lines" option has been added to help better read telemetry values. When toggled on, it replaces the moving vertical lines.
Fixed a crash-to-desktop issue that could occur when users were trying to set a HUD Profile as the global default, but that key did not exist in the “app.ini” file yet.
Graphics
Fixed an issue with vampiric rain (it was not appearing in mirrors).
Fixed an issue where full resolution "Low Res" particle smoke effects were not Z-sorting correctly.
